Volatility in agricultural commodity prices assumes a lot of significance since its associated uncertainty is one of the major factors affecting the income security of producers and traders. The study aims to investigate the fluctuations and instability of the two crops, paddy and wheat, in the states of India. It has estimated instability in prices over the years (2006–2023) for paddy and wheat for the top three producing states by using coefficient of variation (CV), Cuddy-Della Valle index and Coppock’s index. Then it estimates volatility by generalized autoregressive conditional heteroskedasticity (GARCH) framework. It is observed that the average standard deviation of prices across mandis for paddy in a given month is 0.18 and for wheat it is 0.22. Both for paddy and wheat Punjab has the maximum instability among the three states if we consider CV and Coppock’s index. But if we consider the Cuddy-Della Valle index, Madhya Pradesh has the maximum instability for wheat. The noticed unpredictability in the price series of paddy revealed that the value of ARCH (α) has significant term and value of GARCH (β) was also significant for all the price series. The volatility (α + β) was quite persistent of the order of 0.985 in case of Uttar Pradesh. In case of wheat Punjab has the maximum value 0.95 signifying explosiveness. In case of wheat Punjab has the maximum value 0.95 signifying explosiveness.

The purpose of the study was to examine the factors affecting eating behavior of adolescents aged 17–19 years, residing in a college hostel and to assess the effectiveness of nutrition education in improving their knowledge, attitude and practices (KAP).

A convenient sampling technique was used to recruit 200 adolescent female participants of age 17–19 years. The obesity and underweight status of the participants were assessed using body mass index (BMI). Diet history was obtained using a 24-h dietary recall and food frequency questionnaire. A standard pretested questionnaire was used to analyze the factors affecting the eating behavior of adolescents. A nutrition education program was conducted to improve the KAP of the adolescents. A structured questionnaire was used to assess the improvement in KAP after the education program. Descriptive statistics was used to examine the factors affecting eating behavior. Paired t-test was used to check the effectiveness of the nutrition education program.

The findings of the study indicated that 50.5% of the adolescents were underweight (20%), overweight (12%) and obese (18.5%). The mean nutritional adequacy of the adolescents was 68.1%. Social factor had the highest impact on the eating behavior of adolescents (70.8%), followed by the environmental factor (69.7%). Imparting nutrition education was significant in improving the KAP of adolescents with a p-value < 0.05. Thus, it is necessary to analyze the factors affecting the eating behavior of adolescents and establish corrective measures such as community education intervention programs and awareness programs on healthy eating habits to modify the eating behavior of adolescents.

The dietary intake and the factors influencing eating behavior of the adolescents were assessed considering the transition in the intrapersonal, social and community food environment. The inadquate food intake affected the nutritional status of 50% of the adolescents.The taste, temptation, sight of the food, peer pressure, parental influence and unmindful eating practices majorly influenced the eating behavior of adolescents. Unhealthful eating behavior can increase the risk of chronic diseases during the adolescence and may extend in to adulthood. Hence it is necessary to bring a positive change in the eating behavior of the adolescents through a well planned comprehensive nutrition education program. The findings of the study proved that the knowledge, attitude and behavior of the adolescents could be significantly improved through a well planned nutrition eduation program. Further the study also provide insights to plan and implement community food policies targeted to improve the eating behavior and health status of the adolescents. One of the limitations of the study was, in addition to anthropometric measurements and diet history including biochemical parameters would be a better indicator of nutritional status. The cultural and religious influence on eating behavior would also be studied. In future a study on gender differences on the dietary intake and eating behavior of the adolescents can be conducted.

The study reflects the eating behavior of late adolescents and major factors affecting eating behavior of adolescents residing in college hostel. The findings will add on to the existing knowledge on the factors affecting eating behavior of adolescents. As eating behavior is correlated to the health status of the adolescents understanding the factors affecting eating behavior would help in modifying the eating behavior of late adolescents by implementing appropriate measures and help develop programs and policies that aid in improving the nutritional status. Since nutrition education is effective in improving the KAP of adolescents’ nutrition literacy is imperative in schools and colleges to improve the eating behavior and health status of the adolescents.

The research provides a scientific basis for understanding the factors affecting eating behavior of adolescents and the interaction between personal, social and environmental factors. It also acts as basis to be aware of one’s own eating behavior, modify and model healthy eating behavior. Inappropriate eating behavior in late adolescents can continue into adulthood affecting nutritional status and leading to an increase in the prevalence of diseases and disorders in adulthood. This can affect human potential and capital and thereby economic development. Hence, it is imperative to improve the nutritional status of the adolescents by creating awareness and implementing corrective measures to modify unhealthy eating behavior. The research also supports devising policy and programs regarding the nutritional behavior of adolescents.

Eating behavior is a complex interplay of various factors at multiple levels. The adolescents’ eating behavior correlates directly with their nutritional status. In total, 50.5% of adolescents were malnourished. The nutrient intake of the majority of the adolescents was less than the recommended intake. The mean nutrient adequacy was 68.1%. The quality of the diet was largely affected as they did not include 5–7 food groups in a day. The social factors such as peer group influence and parental influence had the predominant impact on eating behavior followed by environmental factors. The nutrition education program helped improve the nutrition KAP. Hence, it is necessary to create awareness and make policies and programs that can improve the eating behavior of adolescents.

The young population of the globe is defined by individuals aged 15 to 24 years. Based on statistics from the Instituto Brasileiro de Geografia e Estatística (IBGE), the second largest women population among 15 years as well as 19 years was in 2017 only behind 35 and 39 years. At this time, the Brazilian male population was higher. The difficulties of the young generation affected the preceding generation and promoted social dynamism. The worldwide data shows that the generation of young and the digital world have been constantly sought, but in reality, approximately one-third of the population in 2017 had no access to the internet.

Access to good menstrual products is a human rights concern. It is essential for normalising the life during menstrual cycles by making available all the resources necessary for managing them. Sustainable menstrual products are the novel products which can improve the women menstrual lifestyles and reduce the discomfort associated with menstruation. However, these products are not readily adopted by the women due to their perception resulting from various factors. Hence, this study aims to figure out these perceptions, which can promote and hinder the adoption of these products.

A survey was conducted for the purpose of data collection. The study uses questionnaire as a research instrument to gain an insight on women health beliefs towards sustainable menstrual products. Data was collected from the women respondents through convenience sampling. Structural equation modelling was applied to analyse the data.

The findings suggest that women with appropriate knowledge had a positive perception towards the sustainable menstrual products, further leading to positive behaviour. It was also noted that marketing efforts through cues to action had an impact on their behavioural patterns. The policymakers and the marketers can focus on such prospects to advocate the use of sustainable menstrual products so that healthcare is improved.

To the best of the authors’ knowledge, this is the first study that provides a comprehensive framework for analysing the impact of women health beliefs towards behaviour of sustainable menstrual products. The study adds meaningful insights to the sustainable menstrual literature.

The purpose of this paper is to investigate, from a thorough review of the literature, the role of metaverse-based quality 4.0 (MV-based Q4.0) in achieving manufacturing resilience (MFGRES). Based on a categorization of MV-based Q4.0 enabler technologies and MFGRES antecedents, the paper provides a conceptual framework depicting the relationship between both areas while exploring existing knowledge in current literature.

The paper is structured as a comprehensive systematic literature review (SLR) at the intersection of MV-based Q4.0 and MFGRES fields. From the Scopus database up to 2023, a final sample of 182 papers is selected based on the inclusion/exclusion criteria that shape the knowledge base of the research.

In light of the classification of reviewed papers, the findings show that artificial intelligence is especially well-suited to enhancing MFGRES. Transparency and flexibility are the resilience enablers that gain most from the implementation of MV-based Q4.0. Through analysis and synthesis of the literature, the study reveals the lack of an integrated approach combining both MV-based Q4.0 and MFGRES. This is particularly clear during disruptions.

This study has a significant impact on managers and businesses. It also advances knowledge of the importance of MV-based Q4.0 in achieving MFGRES and gaining its full rewards.

This paper makes significant recommendations for academics, particularly those who are interested in the metaverse concept within MFGRES. The study also helps managers by illuminating a key area to concentrate on for the improvement of MFGRES within their organizations. In light of this, future research directions are suggested.

Diesel has traditionally been considered the best-suited and most widely used fuel in various sectors, including manufacturing industries, power production, automobiles and transportation. However, with the ongoing crisis of fossil fuel inadequacy, the search for alternative fuels and their application in these sectors has become increasingly important. One particularly interesting and beneficial alternative fuel is biodiesel derived from bio sources.

In this research, an attempt was made to use biodiesel in an unconventional micro gas turbine engine. It will remove the concentric use of diesel engines for power production by improving fuel efficiency as well as increasing the power production rate. Before the fuel is used enormously, it has to be checked in many ways such as performance, emission and combustion analysis experimentally.

In this paper, a detailed experimental study was made for the use of Spirulina microalgae biodiesel in a micro gas turbine. A small-scale setup with the primary micro gas turbine and secondary instruments such as a data acquisition system and AVL gas analyser. The reason for selecting the third-generation microalgae is due to its high lipid and biodiesel production rate. For the conduction of experimental tests, certain conditions were followed in addition that the engine rotating rpm was varied from 4,000, 5,000 and 6,000 rpm. The favourable and predicted results were obtained with the use of microalgae biodiesel.

The performance and combustion results were not exactly equal or greater for biodiesel blends but close to the values of pure diesel; however, the reduction in the emission of CO was at the appreciable level for the used spirulina microalgae biodiesel. The emission of nitrogen oxides and carbon dioxide was a little higher than the use of pure diesel. This experimental analysis results proved that the use of spirulina microalgae biodiesel is both economical and effective replacement for fossil fuel.

Framed under the upper echelons theory, the purpose of this paper is to examine the effect of board characteristics on the adoption of the global reporting initiative (GRI) guidelines for corporate disclosure and, consequently, their effect on the company’s market value.

To achieve the research objective, the authors investigated the impact of certain important board characteristics, such as board independence, size, gender diversity and director skills. The authors examined the adoption of GRI guidelines by 371 companies based in Latin America. Using logistic regression and panel data analysis, the authors tested five hypotheses.

The findings can confirm the upper echelons theory, showing that directors have an important role in determining environmental policies and strategies in their companies. The authors confirm that three characteristics affect GRI adoption in Latin America: independence, gender diversity and skills of board directors. The authors also found that companies that adhere to the GRI tend to perform better in terms of market capitalization.

Managers who want their organization to perform better in terms of GRI disclosure must understand that characteristics such as board independence, gender diversity and directors’ skills play a significant role in the company adopting the GRI for corporate disclosure. Furthermore, managers must be aware that by adopting the GRI, the company increases its market value through market capitalization.

The literature is still unaware of how the adoption of GRI can bring financial returns to organizations that adopt this type of standard to disclose their corporate reports. To the best of the authors’ knowledge, this is the first empirical paper to investigate the antecedents and consequences of GRI adoption in Latin America.
